Briefly stated, a hydraulic ram operated crosshead, linked to a pair of pivotally connected or hinged horizontally movable plates which normally stand with their faces in a'common plane, is moved bodily for apredeterrnined distance by the ram to compress the scrap metal in a longitudinal direction into a vertical right angled corner. At the end of the predetermined bodily movement of the pair of hinged plates, the further movement of the pivotal support for the plates is stoppedand the continued movement of the ram' piston swings the plates forwardly and laterally to a position at right angles to one another to formthe metal into a square prism, which is further compressedin a vertical direction by a vertically supported hydraulic ram.

In-Fig. l, in which the general form of the apparatus-is illustrated, a housing 5 encloses the operating mechanism of the baler, a cab 6 contains thecontrol apparatus, and a housing '1 carries the power unit. The housing 5 opens into a baling bed 3, comprising a bottom plate 4, a fixed side plate 8, and a hopper [9, having a swinging side plate 9, and a top plate or cover [0. A support l I for a vertical cylinder [2 is secured to the front end of the bed. Fixed end plates It extend laterally from-one side of the bottom and cooperate with the swinging side plate 9 and the cover [0 to form a loading hopper IQ for the lower longitudinal channel members [7, connected by cross-channels 18. A hydraulic cylinder 2|] is located about the central longitudinal axis of the-rectangular frame with one end extending through and supported by arr-end plate 2! secured to the members of the rectangular frame.

The cylinder is secured at its inward or forward end bybo1ts-22 to cross-beams 23. The beams 23 are'secure'd to vertical posts 24, attached to the upper and lower frame members I5 and ii. A

piston rod- 25 is attached toa head 26. The piscomprising vertical frame members 29, connected between horizontal frame members 38. The frame members 30 terminate in right angled supports 3| for a pair of shafts 32, each carrying a pair of rollers 33. This structure is clearly shown in Fig. 8. Rigid arms 34 are secured to each of the frame members 30. Each of the rigid arms 34 is connected with a pivotal shaft 35. Each end of the pivotal shaft 35 extends through one end of a pivotal link 33. The opposite ends of the links 35 engage a second shaft31 extending parallel with the shaft 35. A roller 38 is mounted upon each end of each shaft 31. Each roller 38 rides against a track plate 39 secured to an adjacent frame member 15 or H. Two angular links 40, having extended ends 4|, are connected at one of their ends with the shaft3'la. Each, angular link 30 is pivotally supportedbetween its ends upon a shaft 42. The opposite ends of each shaft 42 are each supported in an angular boss 43 formed upon a longitudinally movable beam 44. Stop lugs 35 secured to and extending inwardly from each beam are normally engaged by the extended end ll of the angular link 40.

An outwardly flared loop 46 is provided in the forward end of each track plate-to receive the rollers 38 for the purpose. hereinafter described.

A hinge post 50 is supported between upper and lower plates and 52 which are secured between the upper and lower longitudinally movable beams 44. A pair of heavy fiat faced plates 55 with interleaved hinging surfaces 56 is supported by the post 53. The combined area of the plates 55is equal to the area defined by the walls of the baling bed 3 in its closed position. Laterally pivoted links 51 are connected between the front face of the rectangular plate 21 and the rear faces of the hinged plates 55- adjacent the outer edges thereof. The links. 51 operate in response to relative bodily movement of the plate 21 and hinge post 50 to swing the plates 55 forwardly and inwardly toward each other.

In the operation of the parts above. described, pressure against the rear end of the piston 25 will move the plate 21 forwardly. This movement will be transmitted by the tie rods 28, comprising the frame members 29 and 30, through the arms 34, to the links 36: and 40, the shaft 42, and to the longitudinally movable beams 44-. Since the pivot post 50 for the swinging plates 55 is carried by the beams 44, these plates will remain in a plane to present a flat surface to the contents of the baling bed inthe: preliminary movement of the parts. At a predetermined position in the first movement of the. parts, therollers 38 will be forced into the looped ends 45 of the track plates 39 to stop the forward movement of the rollers 38, the. beams. 44, and the hingepost 50. At this point, continued pressure upon the piston will transmit further movement through the tie rods 28, to the plate- 2-1, 'dueto the angular displacement of the links. 36 and 40; This position of the parts is shownin. Figs. 4 and 5. This final movement of the plate 21; will operate through the. links 51' to swing the. plates.

side faces of the sidewalls. have the same radius.

of curvature as the arcs proscribed by the outer edges of the plates 55 in their swinging movement. This insures intimatecontact between the edges of the plates and walls. which will prevent.

back flow of the baled. material. The. side Walls 4 60 and BI are joined at their forward edges to define two sides of a square prism 64, the other two sides of which are formed by the faces of the plates 55.

As shown in Fig. 6, a rectangular door 10 is supported on trunnions H within a rectangular opening I5 in the side wall 6| of the prism 64 to swing outwardly and downwardly, as shown in Fig. 6. A rectangular plate 16 is rigidly attached to and extends at. right angles to the door 10. In the closed position ofthe door 10;. the plate (6 lies flush with the bottom plate l. A rectangular housing 18 is mounted upon the top plate 62 and opens. downwardly therethrough into the forward end of the baler (Fig. 4). A square pressure block 80. is carried upon the lower end of a piston rod 8i, movable in the vertical cylinder l2, mounted upon the housing 18. The face area of the pressure block is the same as the area defined between the faces of the hinged plates 55 on two sides of the prism 64, and the inner faces of the sides 60 and 6|= as the other sideswhen the plates 55 are in their extreme forward position. The downward movement of the. pressure block 80 presses the material in the prism 54 against the rectangular plate '56 to complete the square prism bale, which is then discharged bydropping the rectangular door 10. The movement of the door 75 is controlled by a pair of hydraulic cylinders 85, the. piston rods 8"! of which are journaled on sides of the door 10, the cylinder being journaled. on the door frame. verticals 88. Fluid pressure in the lowerends of the cylindersraises. and. closes the door 'Hlwhile fluid pressure in the upper ends of the cylinders. opens the door 19.

The loading hopper l9, shown open in Fig. '7, is controlled as to open and. closed position by'a pair of cylinders journaled to the base at 9],,

and having piston rods 92 journaled to the under and outer part of the bottom and side panel -9. The. bottom 9 becomes the side wall of the baler bed 3, and the side wall [0 becomes the cover for the baler bed 3 when the hopper is swung inwardly about the trunnion 94.

The hopper. l9v being open; scrap metal is placed in it and'in the baler bed 3 to any height not greatly exceeding the height of the hopper top plate 10. The swinging hopper I9 is then closed by applying liquid under pressure to the lower part of the. cylinders 93. When the hopper, side wall I0 and bottom wall 9 are swung inwardly about the trunnion. 9d, the side wall 10 becomes the cover, and the bottom wall 9 becomes. the

side. wall of the-baler bed: 3. As the result of this closing operation, the loose material to be baled. isreduced to about one-half of its normal loose size.

After the baler bed 3: isenclosed on the bottom, top and sides, the presser plates 55 move for.- ward. To accomplishthe forward movement ofv the presser plates 55, fluid is forced into the cylinder 23, causing, all: of the associated parts to moveforward through pressure applied from one. part to another in the following order: The piston: rod 25, its. crosshead 27, push links 511 and hinged. presser plates 55. The. crosshead 2! also acts upon the rods 28, yoke frame members 29 and 3B, rigid arms 34, links 36 and 43, cross-shaft 42 longitudinal movable beams 44, lower and upper crossbars 5.-l and-.52, and the vertica-l.press-- er plate pivot 50.

When all of the parts enumerated aboveihave. moved forward. to a position'in which the rollers 38 pass into the depressions 46', the beams 44,

the'crossbars vandi'52', theflvertical presser plate .pivot 5Bstop their forward movement, while.

thecrosshead 21 and the push links 51.- continue to move forward. 'I'hiscausesthepresser plates 55 to fold about their pivot 50 until therightand 1 left presser plates stand at right anglestoone another. As the two halves .of the presser plate 55 swingv inwardly, their router:- vertical edges,

ment, fluid pressure is applied-to the top of ,the
